Here's the full paper, which has a lot of details missing from the summary linked above: https://metr.org/Early_2025_AI_Experienced_OS_Devs_Study.pdf

My personal theory is that getting a significant productivity boost from LLM assistance and AI tools has a much steeper learning curve than most people expect.

This study had 16 participants, with a mix of previous exposure to AI tools - 56% of them had never used Cursor before, and the study was mainly about Cursor.

They then had those 16 participants work on issues (about 15 each), where each issue was randomly assigned a "you can use AI" v.s. "you can't use AI" rule.

So each developer worked on a mix of AI-tasks and no-AI-tasks during the study.

A quarter of the participants saw increased performance, 3/4 saw reduced performance.

One of the top performers for AI was also someone with the most previous Cursor experience. The paper acknowledges that here:

> However, we see positive speedup for the one developer who has more than 50 hours of Cursor experience, so it's plausible that there is a high skill ceiling for using Cursor, such that developers with significant experience see positive speedup.

My intuition here is that this study mainly demonstrated that the learning curve on AI-assisted development is high enough that asking developers to bake it into their existing workflows reduces their performance while they climb that learing curve.

I'm the developer of txtai, a fairly popular open-source project. I don't use any AI-generated code and it's not integrated into my workflows at the moment.

AI has a lot of potential but it's way over-hyped right now. Listen to the people on the ground who are doing real work and building real projects, none of them are over-hyping it. It's mostly those who have tangentially used LLMs.

It's also not surprising that many in this thread are clinging to a basic premise that it's 3 steps backwards to go 5 steps forward. Perhaps that is true but I'll take the study at face value, it seems very plausible to me.
